The main functions of phosphoric acid:
1. Phosphoric acid is the raw material for the production of important phosphate fertilizer (calcium superphosphate, potassium dihydrogen phosphate, etc.), and also the raw material for the production of feed nutrients (calcium dihydrogen phosphate).
2, treat the metal surface, generate insoluble phosphate film on the metal surface, in order to protect the metal from corrosion.
3, mixed with nitric acid as a chemical polish, to improve the finish of the metal surface.
4, the production of washing supplies, insecticide raw material phosphate ester.
5, the production of raw materials containing phosphorus flame retardant.
6, phosphoric acid is one of the food additives, in food as a sour agent, yeast nutrition agent, cola contains phosphoric acid. Phosphates are also important food additives and can be used as nutrient enhancers.
7. Phosphoric acid can be used to make phosphate-containing drugs, such as sodium glycerophosphate.

Phosphoric acid or orthophosphoric acid, chemical formula H3PO4, molecular weight 97.994, is a common inorganic acid, is a medium strong acid. It is obtained by dissolving phosphorus pentoxide in hot water. Orthophosphoric acid is obtained commercially by treating apatite with sulfuric acid. Phosphoric acid dehydrates easily in air. Heat loses water to pyrophosphoric acid, and further loses water to metaphosphate.
